Does he tell you he loves you when you least expect it?Does he flutter your heart when he kisses your neck?No scientist or biologyIt's obvious when he's holding meIt's only natural that I'm so affected

And my heart won't beat againIf I can't feel him in my veinsNo need to question, I already know

It's in his DNA, D-D-D-DNAIt's in his DNAAnd he just takes my breath awayB-b-b-breath awayI feel it every dayAnd that's what makes a manNot hard to understandPerfect in every wayI see it in his faceNothing more to sayIt's in his D-D-D-DNA

It's the blue in his eyes that helps me see the futureFingerprints that leave me covered for days, yeah, hey, yeahNow I don't have any first degreeBut I know, what he does to meNo need to work it out, it's so familiar, oh, oh, oh

And my heart won't beat againIf I can't feel him in my veinsNo need to question, I already know

It's in his DNA D-D-D-DNAIt's in his DNAAnd he just takes my breath awayB-b-b-breath awayI feel it every dayAnd that's what makes a manNot hard to understandPerfect in every wayI see it in his faceNothing more to sayIt's in his D-D-D-DNA

It's all about his kissContaminates my lipsOur energy connectsIt's simple geneticsI'm the X to his YIt's the color of his eyesHe can do no wrongNo, he don't need to tryMade from the bestHe passes all the testsGot my heart beating fastIt's cardiac arrestHe's from a different strainThat science can't explainI guess that's how he's madeIn his D-D-D-DNA

It's in his DNA, D-D-D-DNAIt's in his DNAAnd he just takes my breath awayB-b-b-breath awayI feel it every dayAnd that's what makes a man (what makes a man)Not hard to understand (to understand)Perfect in every way (in every way)I see it in his face (in his face)Nothing more to say (nothing more to say)It's in his D-D-D-DNA
